We extend the classical notion of special polynomials to elements of Weierstrass-like extensions and present algorithms for reduction in such extensions. As an application of these results, we derive some new formulae for integrals of powers of ℘.}, booktitle = {Proceedings of the 2026 International Symposium on Symbolic and Algebraic Computation}, pages = {114–123}, numpages = {10}, keywords = {D-algebraic function; symbolic integration; reduction}, location = { }, series = {ISSAC '26} }
